energy is the energy of motion. Any object that is moving
has kinetic energy. This category of kinetic energy will
be used when the energy is contained in the motion of a
single object or in the motion of a group of objects
that act as a single object.
types of energy are often classified as being a type of
kinetic energy, since their energy is due to the motion,
but there are more than one object involved.
of the most common examples of the energy of this type are:
single object that is moving has kinetic energy.
wind is made up of air molecules. Even though there
are many of these air molecules, energy of motion is
contained in all of the molecules moving as a single
mass of air.
is the vibration or motion of air molecules moving back
and forth. Again, these molecules act as a single mass
